Merge #11133: Document assumptions that are being made to avoid division by zero
55509f1 Document assumptions that are being made to avoid division by zero (practicalswift)
Pull request description:
Document assumptions (via `assert(…)`:s) that are being made to avoid division by zero.
Rationale:
* Make it clear to human reviewers and non-human static analyzers that what might look like potential division by zero cases are written the way they are intentionally (these cases are currently flagged by various static analyzers).
